The scholars started from a point of view that theyself were the male and realizeded that the female's beauty is a latent harm to the society of males.Because of it,the scholars gave the female some effective criterion of ethics and behavior. So the female could walk on this road voluntarily and became a controlled and enslaved role.Besides it, the scholars bounded and fixed the female's station in accordance with the given distinction of production, labor, politics and education between the male and felmale.It became a theory starting point of ethics that males and husbands the honour, females and wives the humble in the aftertime of bimillennium.

在对女性角色的认识上，先秦诸子从自己为男子的角度出发，意识到了女性的容貌之美及其对男性社会的潜在危害；为此，诸子便自然要给予女性一套行之有效的德行规范，并制定对她们进行养成教育的具体方法和途径，从而使女性自觉自愿地行由其径，成为男性驾驭、压迫和奴役的角色；先秦诸子还从自己的思想主张出发，依据男女在生产劳动、政治参与、接受教育以及家庭生活等诸多方面的既有差别，对女性地位予以全面界定，这成为后世两千年来男女、夫妇尊卑分明的伦常观念的理论起点。

In this paper, we construct the differential equation to solve the unconstrained optimization problem. Such methods solving the ill-conditioned problems are very effective. It indicates that the asymptotically stable region of explicit the Euler method to solve the differential equation equals to the descent region of the gradient method to solve the original unconstrained optimization problem.

我们发现，在用Euler方法求解二次优化问题的等价动力系统的方程时，由方法的步长确定的稳定区域对应于这些方法所得到的迭代公式的步长满足单调下降算法的条件确定的单调下降区域，因此我们可以利用这个性质构造解无约束优化问题的数值方法而不采用标准的常微分方程的数值求解公式。

The model of programmed crystallization of SPM was proposed based on the moment transformation of the population considering the agglomeration. The optimal temperature-time curves in a batch crystallizer which maximized the terminal mean size and mean weight size can be determined from the application of the Pontryagin Maximum Principle. The calculated crystallization results heating under optimal temperature were compared with ones under linear or natural heating temperature.

根据第四章所得到的螺旋霉素晶体二次成核和晶体生长和布朗扩散引起的聚集动力学，利用第六章所描述的晶体尺寸分布的各阶矩对时间的一阶导数所构成的自封闭的一阶常微分方程组，采用庞得里亚金极大值原理，以温度为控制变量，在满足某些约束条件下，以最大平均尺寸和最大晶体重量平均尺寸为性能指标，计算出了螺旋霉素间歇结晶的最优温度—时间曲线，并同线性加热和自然方式进行了比较。

What balance we strike --- whether we build on the blessings, ad progress into an ever-increase of the good things on the positive side, or whether we magnify the miseries until our life sinks to what an old nurse of mine used to call a "depressingness" on the negative side --- this issue can depend to a surprising extent on what spirits we create with words.

或：我们是从积极的方面出发，依赖上天的恩赐，使好事不断积累，还是从消极方面出发，使痛苦不断扩大，直到我们的生活沉沦到灰心丧气的境地，正如我的一个老保姆过去常说的那样，究竟如何选择，这个问题会在惊人的程度上取决于我们用词创造了什么样的情绪。

Media Help Everyday we are exposed to the steam often divided into two, one, the boiler steam - saturated steam 2, thermal power plants out of steam - superheated steam 1, a relatively stable temperature and pressure saturated steam, temperature lower than 250 ℃, working pressure lower than 1.6Mpa 2, superheated steam temperature and pressure changes of a high base temperature up to 400 ℃, working pressure is lower than 4.0Mpa For the first steam, we usually use soft sealing steam solenoid valve as follows: Structural characteristics This valve is a valve and Balance valves main valve by the two vice components with the second open valve Pilot solenoid valve Heat: electromagnetic part, some with special high temperature seals and sealing materials, electrical materials, and apply a variety of insulation measures Wear: selection and reasonable Globe Valves guidance suite valve cup and clever use of fluid lubrication, reduce wear, increase life expectancy Resistance to condensation: condensation of steam pipeline valve on the steam water is an important factor in action, the valve will not affect the condensation water Other uses - soft sealing steam solenoid valve This series solenoid valve can Safety valves be widely used in textile, printing, chemicals, plastics, rubber, pharmaceutical, food, building materials, machinery, electronics, surface treatment and research sectors and bathroom, dining room, air conditioning automatic control system.

介质说明日常生活中我们接触到的蒸汽常分为两种，1、锅炉蒸汽-饱和蒸汽 2、热电厂出来的蒸汽-过热蒸汽 1、饱和蒸汽温度压力相对稳定，电动阀门执行器温度低于250℃，工作压力低于1.6Mpa 2、过热蒸汽温度压力变化基数较大温度最高可达400℃以上，工作压力则低于4.0Mpa 对于第一种蒸汽，我们通常会选用氧气专用阀、铜阀门软密封的蒸汽电磁阀如下：结构特点本阀是由副阀和主阀两大部件构成的先导式二次开阀的电磁阀耐热：电磁部分、密封件部分用特种耐高温电工材料和密封材料，并应用了各种隔热措施耐磨：选材合理，电站阀门阀杯和导向套间巧妙地利用流体的润滑作用，减少磨损，提高寿命耐冷凝：蒸汽管道的冷凝水是影响蒸汽电磁阀动作的重要因素，本阀则不受冷凝水影响其他用途-软密封蒸汽电磁阀本系列电磁阀还可广泛地应用平衡阀纺织、印刷、化工、塑料、橡胶、制药、食品、建材、机械、电器、表面处理和科研部门以及浴室、食堂、空调等自控系统。

The technical characteristic of a pendulum drill assembly is to lose "penetration rate"in order to get"dropping angle", but sometimes a pendulum drill assembly can't meet the need of drop—off hole angle, which results in longer completion well cycle and more drilling cost.

防斜打直是常遇到的钻井技术问题，防斜的钻具组合是满眼钻具，纠斜的钻具组合是钟摆钻具，当满眼钻具满足不了井斜控制的要求，就必须强迫起钻换钟摆钻具，而钟摆钻具的技术特点是损&快&保&直&，有时还达不到纠斜要求，导致较长的建井周期和较高的钻井成本。

As reformers often do, she describes her revolution as returning the Rockefeller Foundation to its roots—in this case to the "scientific philanthropy" of its founder, who said that the "best philanthropy is constantly in search of the finalities—a search for a cause, an attempt to cure evils at their source."

就如改革者常做的，她描述她的改革是返回到洛克斐勒基金会创世时的初衷：创始人所说的科学的慈善机构，即&最好的慈善事业是一贯的追求这样一个结局：从根源上征服魔鬼&

Also have an individual in addition " the member that buy on sb's behalf ", they have the VIP member card of each ritzy member card of big market, brand commonly, can not hit in new money dress when folding with 6 fold, the 8.5 price average that lose; In the meantime, they also of haunt suburb " the inn that throw money " wash money with the 1 price that tuck up, hang on the net to sell next.

此外也有个人&代购员&，他们一般都有各大商场的最高级会员卡、品牌的VIP会员卡，能在新款服装都不打折的时候以6折、8.5折的价格买进；同时，他们也常到郊区的&甩货店&以1折起的价格淘货，然后挂在网上卖出。

Pigs are pink. Only the chameleon has no color of his own. He is purple like the heather, yellow like a lemon, even black and orange striped like a tiger! Then one day a chameleon has an idea to remain one color forever by staying on the greenest leaf he can find.

他认为人的视觉影像是非常重要的，在他的文章中，他常说：儿童在图画书中会体验到的是一连串已结构成形的幻想，但这些幻想却会激发孩子内心深处的感觉与想象。

北极圈内苍白倾斜的阳光，漫过清寒微风的山谷、常绿的寒带茂密丛林……挪威，如此遥远的国度，遥远到你脑海里只有这样一些旷远而模糊的图画，而没有关于它的任何具体的细节想像。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
